large and advantageously situated. No deposits of antimony ores
have been found in the United States which entirely fulfill these con
ditions, and as a result practically all the antimony metal used here
is imported from European smelters, mostly from England. The
ores for these smelters come largely from China, Mexico, and France.
So long as the war lasts, and especially so long as sea traffic is dis
turbed, the production will be curtailed and prices raised, for the
use of antimony in type metal, and especially in bearing metals, is
fixed and will continue. Other uses, such as the making of coffin
trimmings, which consume a surprisingly large quantity of anti
mony and from which there is no secondary recovery, might con
ceivably turn to aluminum or other metals as substitutes.
For several years the production of antimony in the United States
from domestic ores has been confined to that contained in antimonial
lead and small quantities recovered in the electrolytic refining of
copper and lead. A production of antimony from foreign ores—
which can only be estimated—is also made. The antimonial lead is
mostly a by-product in the smelting of the precious metals, and
efforts are made to save all possible, so that this production can not
be largely increased. Th^quantity saved in electrolytic copper refin
ing can probably be increased, though not enough to make it a
serious factor in the market.
The production, recovery, imports, and approximate consumption
of antimony in the United States for 1913 are shown in the following

Besides these items, more than 1,000 tons of oxide and salts of
antimony, valued at over $117,000, were imported.
It is probable that under the pressure of high prices attempts will
be made, as in 1900-7, to work American deposits. If this can be
done without great initial outlay, some antimony miners will prob
ably make good profits; but it may be only a few months before
prices will be back to or near those prevailing during the last six
or seven years.
